The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Jaconé. This is a solid stretch of days ahead, but it’s not all plain sailing. We’ve got a few bits of clean, offshore magic to chase, but also some big, powerful swells that will only be for the well-experienced crew.
The first few days are a slow warm-up. Monday the 3rd is a bit of a dud with small, wind-affected waves. Tuesday the 4th is small and clean in the morning, but the swell is tiny and weak. The real story starts to build from Wednesday the 5th. That morning, the wind is glassy offshore, and we’ve got a 3ft south swell with a solid period. The combined energy is pumping at 581 (moderate energy), and it’s looking clean. This is a good window for an intermediate surfer to get a few fun ones.
Thursday the 6th and Friday the 7th mornings both have clean conditions with good offshore winds, but the swell is average. Saturday the 8th is similar.
Then comes Sunday the 9th *of August* – that’s the standout. The morning brings a 3ft south swell, but the period is 18 seconds, which is very long period groundswell. The energy reading is 1091 (strong energy). The wind is light offshore from the NNE. This is classic, clean, powerful long-period swell. It will be best at the peak or a reefy section, not a straight beach break, because that long period can make waves close out if it’s too shallow. The afternoon glass-off with a 6ft SSW swell (16-second period, energy at 1907) is for the more experienced crew. Crowds are a possibility here, so get in early.
Monday the 10th and Tuesday the 11th are a write-off. Strong onshore winds and rain ruin the potential, even though the swell is still present.
Wednesday the 12th *of August* is interesting. The morning is too big at 10ft and cross-shore winds, making it messy and dangerous. The afternoon, however, is a gem for experts: 8ft south swell, 11-second period, with light offshore winds. The energy is 1871 (very strong). This is big, powerful, and clean. Only for those who know what they’re doing.
The rest of the second week sees a mix of average conditions and some pulsey swells. Thursday the 13th has a clean 7ft morning with light offshore wind – good for experienced surfers. Then the 17th and 18th of August bring another big pulse: 8ft swell on the 17th with glassy morning conditions, and another 8ft day on the 18th with clean cross-offshore wind. These are powerful, expert-only days.
If I had to pick the *best* on offer: Sunday the 9th of August for the perfect long-period, clean morning, and the afternoon of Wednesday the 12th for the bigger, expert-level, clean waves. The 17th and 18th are also serious swells for the experts.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
